PROBLEM TO BE SOLVED: To provide an inexpensive long-term sustained release medicine epidural placement system with a simple configuration, which prevents fall of ADL and a risk of infection to be caused by frequent epidural puncture or catheter placement and is minimally invasive and excellent in biocompatibility and safety.SOLUTION: This long-term sustained release medicine epidural placement system 1 for placing a long-term sustained release medicine 40 in an epidural cavity 33 in epidural anesthesia or epidural block includes: at least string-like catheter type placement members 20 and 20A-20C which are formed of a medically compatible biodegradable material and carry a long-term sustained release medicine inside releasably in a sustained manner and an injection means 10 which includes an epidural needle comprising a needle assembly having an inner needle 16 inserted in an outer needle 15, or a CV port. The string-like catheter type placement members are held in the outer needle of the injection means and are extruded into and placed in the epidural cavity, from the outer needle pierced from the back of a patient and inserted into the epidural cavity.COPYRIGHT: (C)2012,JPO&INPIT【課題】簡単な構成により安価で、頻回な硬膜外穿刺やカテーテル留置によるADLの低下や感染のリスクをなくし、低侵襲性、生体適合性及び安全性に優れた長期徐放型薬剤硬膜外腔留置システムを提供する。【解決手段】本発明の長期徐放型薬剤硬膜外腔留置システム1は、硬膜外麻酔又は硬膜外ブロックを行う際に硬膜外腔33に長期徐放型薬剤40を留置する長期徐放型薬剤硬膜外腔留置システムであって、医療適合性の生分解性素材から形成され、長期徐放型薬剤が徐放自在に内部に担持された紐状カテーテルタイプ留置部材20、20A~20Cと、 外針15内に内針16が挿入される針組立体からなる硬膜外針又はCVポートを含む注入手段10と、を少なくとも備え、紐状カテーテルタイプ留置部材は、注入手段の外針内に収容され、患者の背面から穿刺されて硬膜外腔に挿入された外針から硬膜外腔に押出されて留置される。【選択図】図2
